摘要：

在对60 MN自由锻水压机进行改造过程中发现，拉紧板变形严重及主工作台面磨损严重，针对此现象提出了一种主工作台面结构的改进方案。基于ANSYS数值模拟软件，对两种结构主工作台面在实际工作状态下的变形规律及应力分布规律进行数值模拟研究，并对两种结构主工作台面在制造、安装、使用、维修及维护等方面进行工艺性能对比分析。分析结果表明，整体结构主工作台面在承受60 MN压力时虽然两侧出现2.058 mm的翘起，但可以明显增大拉紧板工作时的受力面积、减小拉紧板变形量及所受应力，同时具有有效防止氧化铁皮渗漏、提高润滑效率等优点，整体结构主工作台面的改进方案优于分体结构。

When the 60 MN free forging hydraulic press was reconstructed, the serious deformation of the tension plate and the serious swear of the main working table were found. For the above issues, an improved scheme for the main working table was put forward. Therefore, the laws of the deformation and the stress distribution with the two main working tables in the working state were analyzed by software ANSYS. Meanwhile, the processing properties of the manufacture, installation, usage and maintenance for main working tables were studied. It is concluded that when the overall structure of the main working table is under 60 MN pressure, even though both sides appear the 2.058 mm deformation, it can obviously increase the force area by the tension plate, decrease the deformation and the stress of tension plate. In addition, it embodies the advantages of the prevention of iron oxide leakage and the improvement of the lubrication, etc. The final result shows that the improved whole structure of the main working table is better than the fission structure.
